Recording a mark with the rising and falling edges varied based on previously recorded control data

摘要

Optimum edge recording methods are previously held in a control data zone on the recording medium, and one of the methods is selected in a write mode by referring to the recorded methods. An information recording apparatus for forming a recording mark by converting an energy beam to a multi-pulsed train and irradiating the beam onto the recording medium includes that change-over can be realized between mark edge control based on control of both pulse edge positions and mark edge control based on control of one of the pulse edge positions.
